Jack under rear springs?

Can I safely use my trolly jack under the rear springs? Seems like a nice big flat area to lift the rear tires with

You can try, but its not really all that useful since most of your effort will be spent compressing the spring into the car. As long as you have a rubberized pad on the jack, you can just use the normal jacking position between the wheels.

If you have a long enough floor jack, you can raise the entire rear end by using the center position (under the spare tire area). Then slide a pair of jack stands at the jacking spots by the wheels.

No, that is not a safe jacking point. Use the correct factory specified jack points on the car.

The springs are already compressed from the wieght of the car. Useing this point is fast because it lifts the car immediatly instead of spending the effort decompressing the springs away from the car when you use the standard point. I just wasn't sure about the integrity of the spring mounts. I thought since the down force was on them already that they would handle the reverse.

like the others said, jacking up at the spring points are kind of useless lol. goobers idea is solid. jack in right in between, will be a silver square spot to use as jack point. thats where i jacked my rear up when installing my coils

no... as you lift the jack, the weight of the car shifts, eventually, that jacked spring and the opposite corner are supporting more and more of the weight.

As there's more weight putting pressure, the spring compresses.

It's only fast, if your intention is to take off the wheel.

No... No... What do you think happens to the spring when you go over a bump? I think jacking it would cause them to be under a dangerous amount of stress, if the jack is uneven it would probably shoot out and drop the car down. Why wouldn't you spend a few extra seconds to jack the car properly?

It's not safe, just don't do it, period. No need to even argue the point.

Your eagerness to save 30 seconds of jack time could cost you an arm or a leg... literally.

Honda specified the correct jack points, USE THEM!
